The role of exenterative surgery and urinary diversion in persistent or locally recurrent gynecological malignancy: complications and survival

Treatment options in patients with persistent or locally recurrent cervical cancer are limited. The aim of this study was to determine the chance of cure and associated morbidity following pelvic exenteration.

Arterial hypertension and proteinuria in pediatric chronic kidney disease

A variety of chronic kidney diseases tend to progress towards end-stage kidney disease. Progression is largely due to factors unrelated to the initial disease, including arterial hypertension and proteinuria. Intensive treatment of these two factors is potentially able to slow the progression of kidney disease. Blockers of the renin-angiotensin-aldosterone system, either converting enzyme inhibitors or angiotensin II receptor antagonists, reduce both blood pressure and proteinuria and appear superior to a conventional antihypertensive treatment regimen in preventing progression to end-stage kidney disease. The most recent recommendations state that in children with chronic kidney disease without proteinuria the blood pressure goal is the corresponding 75th centile for body length, age and gender; whereas the 50th centile should be aimed in children with chronic kidney disease and pathologically increased proteinuria.

[11C]Choline PET/CT for targeted salvage lymph node dissection in patients with biochemical recurrence after primary curative therapy for prostate cancer. Preliminary results of a prospective study

INTRODUCTION: In this prospective study we set out to investigate the diagnostic value of [(11)C]choline-PET/CT in patients with suspected lymph node metastases before salvage lymph node dissection. PATIENTS AND METHODS: 15 consecutive patients with rising PSA underwent [(11)C]choline-PET/CT and consecutive open salvage pelvic/retroperitoneal extended lymph node dissection due to uptake of [(11)C]choline in at least 1 lymph node. Mean age was 62.1 (range 53-73). RESULTS: [(11)C]choline-PET/CT results were compared with the histopathology reports and clinical follow-up (mean 13.7 months, range 6-24). Mean time to progression was 23.6 months (range 4-81). [(11)C]choline uptake was observed in nodes along the external and internal and common iliac arteries and in the paraaortic region. A positive histology was reported in 8/15 patients. Only one patient had a PSA nadir of <0.1 ng/ml after salvage surgery. Another patient had stable disease with a PSA of 0.5 ng/ml. Three patients developed bone metastases during follow-up. CONCLUSIONS: This interim analysis indicates that [(11)C]choline-PET/CT may be a useful technique in detection of lymph node metastases when rising PSA occurs after definite prostate cancer therapy. The presented cohort is limited in size, but there is still strong evidence that the patients benefit from [(11)C]choline-PET/CT and consecutive salvage lymph node dissection is rather small.

Treatment and outcomes of urethral recurrence of urinary bladder cancer in women after radical cystectomy and orthotopic neobladder: a series of 12 cases

INTRODUCTION The incidence, treatment, and outcome of urethral recurrence (UR) after radical cystectomy (RC) for muscle-invasive bladder cancer with orthotopic neobladder in women have rarely been addressed in the literature. PATIENTS AND METHODS A total of 12 patients (median age at recurrence: 60 years) who experienced UR after RC with an orthotopic neobladder were selected for this study from a cohort of 456 women from participating institutions. The primary clinical and pathological characteristics at RC, including the manifestation of the UR and its treatment and outcome, were reviewed. RESULTS The primary bladder tumors in the 12 patients were urothelial carcinoma in 8 patients, squamous cell carcinoma and adenocarcinoma in 1 patient each, and mixed histology in 2 patients. Three patients (25%) had lymph node-positive disease at RC. The median time from RC to the detection of UR was 8 months (range 4-55). Eight recurrences manifested with clinical symptoms and 4 were detected during follow-up or during a diagnostic work-up for clinical symptoms caused by distant metastases. Treatment modalities were surgery, chemotherapy, radiotherapy, and bacillus Calmette-Guérin urethral instillations. Nine patients died of cancer. The median survival after the diagnosis of UR was 6 months. CONCLUSIONS UR after RC with an orthotopic neobladder in females is rare. Solitary, noninvasive recurrences have a favorable prognosis when detected early. Invasive recurrences are often associated with local and distant metastases and have a poor prognosis. © 2014 S.

Radical cystectomy and ileal orthotopic bladder substitution after radical retropubic prostatectomy: functional and oncological results

Men with good functional results following radical retropubic prostatectomy (RRP) and requiring radical cystectomy (RC) for subsequent bladder carcinoma seldom receive orthotopic bladder substitution. Four patients aged 62-72 years (median 67 years), who had undergone RRP for prostate cancer of stage pT2bN0M0 Gleason score 6 (n = 1), pT2cN0M0 Gleason score 5 and 6 (n = 2) and pT3bN0M0 Gleason score 7 (n = 1) 27 to 104 months before, developed urothelial bladder carcinoma treated with RC and ileal orthotopic bladder substitution. After radical prostatectomy three were continent and one had grade I stress incontinence, and three achieved intercourse with intracavernous alprostadil injections. Follow-up after RC ranged between 27 and 42 months (median 29 months). At the 24-month follow-up visit after RC daily urinary continence was total (0 pad) in one patient, two used one pad for mild leakage, and one was incontinent following endoscopic incision of anastomotic stricture. One patient died of progression of bladder carcinoma, while the other three are alive without evidence of disease. The three surviving patients continued to have sexual intercourse with intracavernous alprostadil injections. Men with previous RRP have a reasonable chance of maintaining a satisfactory functional outcome following RC and ileal orthotopic bladder substitution.
